Plate I. is a photograph of an extremely interesting bow. Like the preceding example it has the conventional nut and _cambre_. In the matter of ornamentation it is probably unique. It is not only fluted throughout, but is inlaid with a minute mosaic of red, yellow and brown woods. In appearance it reminds one of the straw-work so popular at one period. Inlaid on one side of the nut are seen the Arms of Spain, and on the reverse is the Royal monogram. Mr. Alfred Hill procured this bow with some difficulty in Madrid and was able to trace its pedigree in so far as that it was originally with the instruments made by Stradivarius for the Spanish Court. There is just a shadow of possibility that it may be the actual work of that most glorious craftsman of Cremona. [Illustration: PLATE I.] Its length over all is 27-1/2 in.; the playing length of the hair is 23-1/4 in.; the width of the hair barely 1/4 in. This bow has the most scientific _cambre_ as yet found. Its deviation is 9/16 in. in 26-5/8 in. It is also of more flexible material than the others. The centre bow in Fig. 26 is stamped by Thomas Smith (at last we have a signed specimen), chiefly known for his 'cellos. It was most probably made, however, by Edward Dodd. The head, while possessing a certain elegance, is of a very early type. It is of yellow lance wood and has a very pronounced _cambre_, the deviation being nearly 1/2 in. in 27-1/4 in. The total length is 28-3/4 in., and from the mortices in the head and nut one would suppose that it was intended to take somewhat broader hair than the preceding examples. The date of the bow is somewhere between 1760 and 1780. The other bows in Fig. 26 are viola da gamba bows; the upper one I use frequently myself in certain pieces for that instrument. It is very elegant and I should say is of French make. It is extremely flexible and most adapted to sustaining chords of three notes, as the great distance of the hair from the stick prevents any "grinding" on the middle string. But like all these early bows the hair is much too narrow. The other gamba bow in Fig. 26 is very quaint and appears to be of much earlier date. It is handsomely fluted through the upper two thirds: the lower third being a simple octagonal. A curious feature is that the distance of the hair from the stick gradually diminishes from 1 in. at the heel to 1/2 in. at the point. It has a slight _cambre_, but being of snake wood is quite poker-like in its rigidity. [Illustration: FIG. 26.] As is it impossible to determine the exact date of these bows, one can arrive at no very safe conclusion as to when the movable nut was first introduced. Fetis thinks this important modification came from the East also, and he mentions a cherry wood bow in his possession, made at Bagdad, which has a distinct head where the hair is inserted, and a nut fitting into a dovetail notch in the stick.
